What is the crystal structure for bituminous coal?
Bituminous coal does not have a specific crystal structure because it is composed of amorphous carbon along with varying amounts of other elements like hydrogen, oxygen, sulfur, and nitrogen. This lack of crystalline structure is what distinguishes coal from minerals like diamond or quartz, which have well-defined crystal structures.
What is the crystal structure for coal?
Coal does not have a crystalline structure, crystalline structures are only caused when and untainted sample solidifies from another state, coal is caused by pressure and heat applied over thousands of years to dead animals, as a result it contains high levels of impurities and has a very unpredictable and random structure.
Why do crystals grow better on coal?
Crystals can grow better on coal because coal has a rough surface, providing more sites for crystal nucleation and growth. The impurities and imperfections in coal can also act as nucleation sites for crystal growth, promoting the formation of larger and more defined crystals. Additionally, the chemical composition of coal may provide specific conditions conducive to the growth of certain types of crystals.
What named carbon do diamonds and coal contain?
Both diamonds and coal contain carbon atoms in their crystal structure. Diamonds have a tetrahedral lattice structure, while coal has an amorphous structure.
Is bituminous coal a mineral?
Yes, bituminous coal is considered a mineral because it is a naturally occurring solid substance with a definite chemical composition and crystal structure.
Is coal crystal?
yes
Is coal not a mineral because it has a crystal structure?
No. Coal is not a mineral for two reasons: it lacks a crystal structure and it is organic.

Yes, bituminous coal is considered a mineral because it is a naturally occurring solid substance with a definite chemical composition and crystal structure.
Is graphite made of coal?
Both coal and graphite are made of carbon, but in different molecular structures. Diamond is also made of carbon but in a highly ordered crystal structure.
Coal and diamond are two different forms of carbon which is more dense?
Diamond is more dense than coal. This is because diamond has a more tightly packed crystal structure, making it denser compared to coal which is less compact.
Does coal have crystals?
Yes, coal can contain carbon crystals, which are known as macerals. These can give coal a glossy appearance and may be visible under a microscope. However, coal itself is not considered a crystal because it is an organic sedimentary rock made up of decomposed plant material.
What is the type of crystal structure in coal?
Coal primarily has an amorphous structure rather than a well-defined crystalline structure. It is composed of a complex mixture of organic compounds, primarily carbon, along with varying amounts of hydrogen, sulfur, oxygen, and nitrogen. The lack of a specific crystal lattice distinguishes coal from crystalline materials, though certain forms of carbon like graphite, which can be found in some coal, do exhibit a layered crystalline structure. Overall, coal's structure is more about the arrangement of organic molecules than a typical crystalline form.
Why is coal not a true mineral?
Coal is not considered a mineral because it is organic in nature, formed from the remains of plants. Unlike minerals, which are inorganic and have a crystalline structure, coal does not have a consistent chemical composition or crystal structure. This distinction classifies coal as a sedimentary rock rather than a mineral.
